Abstract

A brake disc comprises two flat, parallel friction rings interconnected by radial and axial ribs, with each ring being formed by at least two joined sectors. A circular flange extends radially inwardly from the rings and has a shoulder for receiving the lip of a flexible cylindrical web extending concentrically back from one end of a central hub. The flange and lip are secured together by a plurality of screws which bear the braking forces, while the flexibility of the web accommodates radial expansions due to the heating of the friction rings.
